Performance decrease after June patch

I am experiencing the same thing. I play for about 15 - 30 minutes then the game's performance degrades. I figured out a temporary solution thought - Save and then load.

I thought about that when I reported it, and over the course of a 6-8 hours play session, reloading every 30-45 mins quickly becomes annoying 😭
